peakPantheR_plotEICFit: Plot samples raw data and detected feature for a single ROI

In peakPantheR: Peak Picking and Annotation of High Resolution Experiments

Description

plot a ROI across multiple samples (x axis is RT, y axis is intensity). If curveFit is provided, the fitted curve for each sample is added.

Usage

peakPantheR_plotEICFit(
    ROIDataPointSampleList,
    curveFitSampleList = NULL,
    rtMin = NULL,
    rtMax = NULL,
    sampling = 250,
    sampleColour = NULL,
    verbose = TRUE
)

Arguments

ROIDataPointSampleList	(list) list of data.frame of raw data points for each sample (retention time 'rt', mass 'mz' and intensity 'int' (as column) of each raw data points (as row)).
curveFitSampleList	(list) NULL or a list of peakPantheR_curveFit (or NA) for each sample
rtMin	(float) NULL or vector of detected peak minimum retention time (in sec)
rtMax	(float) NULL or vector ofdetected peak maximum retention time (in sec)
sampling	(int) Number of points to employ when plotting fittedCurve
sampleColour	(str) NULL or vector colour for each sample (same length as ROIDataPointSampleList, rtMin, rtMax)
verbose	(bool) if TRUE message when NA scans are removed

Value

Grob (ggplot object)

## Plot features in 1 sample without colours

## Plot features in 2 samples with colours
peakPantheR_plotEICFit(
                ROIDataPointSampleList=list(tmp_DataPoints1,tmp_DataPoints2),
                curveFitSampleList=list(fit1, fit2),
